Why Is My House So Dusty?

You know the drill. Every week, there is a day where you sit down with your list of chores and pour over which ones haven’t been done yet. Dusting always seems to get left behind in lieu of cleaning the toilets, washing the dishes or taking care of the pet’s needs.

Nobody likes to dust. And you may be wondering, "Why is my house so dusty?"

In this article, the team at CleanAir will help break down exactly what dust is, and how you can keep your home from getting so dusty, saving you hours of dusting and frustration over your home’s air quality.

Why Your House Is So Dusty

You may not notice how dusty your home is while you are home, but that first whiff of scent when you walk in the door, especially if you’ve been gone for a long time, can tell you a lot about your home’s air quality. If you experience allergies, then dust might be partially to blame as it floats in the air waiting for you to breathe it in.

Dust is a difficult phenomenon to track. You might think that dust is a natural part of owning a home – in which case, you would be surprised to hear that it is actually a symptom of poor air quality. Dust may not be dirt particles, either. (1) Dust can be any number of small particles of debris, meaning the door that was left open all day might not be the culprit. 


“The layer of dust that settles on your furniture can be a combination of many things; tiny particles of dirt, fibers, pollen, pet dander (bits of fur and skin), and even human skin flakes.” - Glenda Taylor

Dust is present in many areas of the home, and when that debris gets stirred up, it will float in the air for hours or days before settling back down all over your furniture, ceiling fans and ventilation system.

There are several reasons why you might be seeing an increasing amount of dust in your home. These reasons range from dander from your pets, to poor air filters and uncleaned upholstery and fabrics in your home.  

  • Windows and Doors

If your windows and doors have a gap between them and the framing, dust may be making its way inside through these small openings. This is not only bad for your home’s energy efficiency; it can also be a symptom of a poor foundation.

You can either get these areas professionally repaired, or as a quick fix, you can apply outdoor caulking around the edges of windows and doors, especially inside areas where you see a visible crack or gap. You should also replace any weather stripping that has been worn down or damaged.

  • Pet Dander

There is no secret that we love our pets. Just like us, however, they shed hair and dander. Even short-haired pets shed; this is a fact of life. This, however, can add to your home’s level of dust and make more frequent dusting necessary throughout the home. There is no real fix for this except for looking at the health of your air conditioning unit because your air filter can help filter pet dander and other debris out of the home.  

  • Poor Air Filtration

Poor air filtration is the No. 1 cause of poor air quality inside a home. If you notice that you have more allergies indoors rather than out, that is a sure sign that something about your ventilation needs to change. Poor air filtration can be caused by several things, but the most common reason your HVAC unit might be suffering is that the filter needs to be swapped out or upgraded.  

  • Carpets and Upholstery

You might be surprised to learn that dust and dirt that sticks to the various fabrics in your home, such as carpeting or upholstery, blankets and towels, may contribute to the level of dustiness in your home.

When you walk in the front door, dirt from your shoes can transfer onto the flooring, and other particles like smoke, skin flakes and dander can settle onto fabrics, making it difficult to dust. When these fabrics are moved or disturbed, it can stir the dust back into the air where it floats for several days at a time.

And you thought dust couldn’t get much more annoying.

You can help eliminate dust from these sources by frequently vacuuming carpeted surfaces, keeping any hardwood floors clean, and encouraging members of your home to take their shoes off at the door. Drapes and other fabrics can also be vacuumed. Some fabrics, such as blankets, towels and heavy-duty curtains can be thrown in the laundry to be washed and dried, removing dust and grime that is woven inside the fabric.

If you want to get rid of dust from these sources permanently, then you may want to consider having your floors professionally replaced with hardwood or laminate and removing any tapestries or drapes.

Air filters are rated based on the MERV system, which stands for Minimum Efficiency Reporting Value. This is a ranking based on how well air filters filter dust, dander and pollen out of the air.

We offer three main types of pleated air filters that cover the needs of most residential and commercial HVAC units: the MERV 8, MERV 11 and MERV 13.

Our MERV 8 Allergen Attacker is best for smaller residences with one or two people and no pets. This air filter is effective at filtering out pollen, large particles of bacteria, dust, mold, and dust mites, keeping your home free of lighter coatings of dust.

Our MERV 11 Allergen Attacker is suitable for homes with pets, especially if there are two or more people living in the space. This is the ideal filter if you do a lot of home cooking or live in an industrial area near roadways and factories. On top of performing the same filtration that the MERV 8 filter does, this filter also efficiently filters pet dander, smog, fumes and pollen.

Finally, the MERV 13 Allergen Destroyer is the best choice for residences with pets, kids and more than two people living in the same home. This is also the ideal choice for individuals with allergies or asthma, or who prefer their home to be spotless and free from dust. In addition to the previous filtration capabilities, this filter also filters out harmful tobacco smoke, virus carriers, microscopic allergies, and car fumes.
